To understand brain network functions, our research program is comprised of two directions: 1) Identifying brain network interactions and 2) Testing causal roles by modulating brain network interactions. For the first aim, we study functional neuroimaging data with network analysis methods to understand brain network functions (Hein, Morishima et al. Science, 2016; Nakataki et al., Neuropsychopharmacology, 2016). For the second aim, we develop a new methodological framework to modulate brain network interactions with non-invasive brain stimulation methods (Fehér, et al., Frontiers Human Neuroscience 2017).

The methods we are using are as follows.

  • Functional MRI
  • fMRI-based functional/effective connectivity analysis
  • EEG
  • EEG-based connectivity analysis
  • Concurrent TMS-EEG/tDCS-EEG/tACS-TMS-EEG
